Definition of IoT Sensors
IoT sensors are devices connected to the internet that can collect and transmit data from their surroundings to a central system. These sensors can measure various parameters such as temperature, humidity, air quality, and more. The data collected by these sensors is then used for analysis and decision-making.
How Do IoT Sensors Work?
IoT sensors work by collecting data from their environment using sensor technology. This data is then sent to a cloud-based platform via the internet. The platform processes the data and generates useful information for monitoring conditions and responding to changes in real-time.
